Four‐Meter Sparks in Air Academic Article uri icon


  • Sparks of 4-m length in atmospheric air were studied, using high-speed image-converter photography, current and voltage measurements, absolute measurements of radiated light intensity, and high-speed image-converter spectroscopy. Correlated results of the various measurements are presented. The energy balance of the spark is discussed. © 1968 The American Institute of Physics.
